EDWARD HANSON BOOOOCK, OF WEST VALE, NEAR HALIFAX, AND JOSEPH SUTCLIFFE, COW GREEN, HALIFAX, ENGLAND` BOBBIN BROACH OR CREEL-PIN.

Specification of Letters Patent.

Patented March 19, 1907.

Application led ctcbei 20,1906. Serial No. 339.757.

To all whom, it may concern.'

Be it known that we, EDWARD HANsoN Boocoox and JOSEPH SUTCLIFFE, subjects of the King of Great Britain, and residing, respectively, at West Vale, near Halifax, and COW Green, Halifax, in the county of York, England, have invented certain new and useful Improvements in Bobbin Broaches or Creel-Pins, of 4which the following is a speciication, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to bobbin broaches or Creel-pins and the object thereof is to provide an improved device of this class designed to avoid in a great measure the breakage which often occurs with the old kind of broaches or creel-pins by reason of the top and bottom nipples, Iwhich are turned solid with the broach or Creel-pin, being broken off in taking it out ofthe creel to remove the empty bobbin, such breakage fre uently occuring if for any reason the broagh or creelpin should fall or be dropped on the floor.

The invention is fully disclosed in the following speciiication, of which the accompanying drawings form a part, in which the separate parts of our improvement are designated by suitable reference characters in each of the views, and in which- Figure 1 is a side view of our improved broach or Creel-pin, and Fig. 2 a longitudinal section thereof.

In the practice of our invention we rovide a broach or Creel-pin a, one end of w 'ch is provided with a head e2 in the usual manner, and the other end of said broach or creelpin is provided with a metal cap or sleeve b, and passing longitudinally through the bro ach or creel-pin is a rod c. The sleeve or cap l) forms a chamber d in that end of the broach or creel-pin with which said cap is connected, and said cap or sleeve projects beyond the body portion of the broach or Creel-pin in order to form said chamber, and the body portion of the broach or creel-pin is provided in said end with a chamber or recess e.

The rod c is provided at the end thereof1 within the chamber or recess e with a head c2, and mounted in the end of the broach or creel-pin formed by the sleeve or cap l) is a flexible nipple This nipple is made, preferably, of lancewood, or it may be made of aluminium or of any other suitable material,

' and the inner end thereof is provided with a bulb or head f2, which is preferably of the form of a truncated cone, and said nipple passes through a hole g in the cap or sleeve the transverse dimensions of which are greater than the transverse dimensions of the nipple f, and the base of the head f 2 bears on the surrounding walls of the hole g, and said base is rounded, so as to facilitate the tipping or tilting of the nipple f, as shown in dotted lines in Fig. 2. f

Bfetxvleen thtJ end of the rod c anfll the heal 2 o t e nip e is lace a s ira spring l)which pressels, ifespeldtively, oh the head f2 of the nipple f and on the head c2 of the rod c, and said heads j' 2 and c2 are respectively provided with lugs or projections f3 and c3, which enter the opposite ends of the spring h. The rod c projects through the opposite end of the broach or creel-pin in order to form the nipple fi, and the spring h, as will be understood, holds both of the nipples f and i in proper operative position.

The end of the cap or sleeve through which the nipple f passes is slightly rounded to allow the broach or creel-pin to pass easily through the bobbin, and with a broach or Creel-pin made in this manner if the same should be accidentally dropped at any time and should strike on the nipple fi the said nipple will yield, as will be understood, being driven inwardly against the operation of the spring h, and if the bro ach or Creel-pin should strike on the nipple f either directly or laterally the said pin will either yield laterally, as indicated in dotted lines in Fig. 2, or will be driven inwardly against the operation of the spring h, and in this way the breaking off of the said nipples, which frequently occurs with the old form of construction, is avoided. It will be observed that the top side of the bulb or head f2 of the nipple f or that part thereof which bears directly on the end of the sleeve or cap l) is flat, and with this construction the spring h always holds said nipple in proper operative position under ordinary circumstances, and if by any reason it is tilted tov one side the spring h Valways returns it to its normal operative position, and

IOO

if an operator should pull the broach too far i outward the pin or nipple f2 will tip over or tilt, as shown in dotted lines in Fig. 2; but

When said broach is released by the operator the spring 7e, Will at once return the nipple f to its normal position.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A broach or Creel-pin provided at its opposite ends With movable nipples, and a tensional device for holding said nipples in operative position.

2. A broach or creel-pin provided at its opposite ends with movable spring-supported nipples.

3. A broach or creel-pin provided at its opposite ends with movable nipples and a spring device which normally holds said nipples in operative position.

4. A breach or creel-pin provided at its opposite ends With movable nipples and a spring which normally holds said nipples in operative position, one of said nipples being movable longitudinally of the broach or Creel-pin and the other being adapted to tilt laterally and also movable longitudinally of said broach or creel-pin.

5. A broach or creel-pin provided at one end with a cap or sleeve through which is outwardly passed a nipple provided with a head adapted to bear on the end of said cap or sleeve7 a movable rod passed longitudinally through said breach or pin and one end of Which projects through the opposite end of the broach or pin to forni a nipple, and a spring placed between the head of the lirstnamed nipple and said rod, said rod being provided With means for limiting its outward movement.

In testimony that We claim the foregoing as our invention We have signed our naines, in presence of the subscribing \\f.itncssos, this 10th day oi' October, 1906.
